Vertical storage tank with two heat exchangers

 

Vertical storage tank with two heat exchangers

Τhe two heat exchangers storage tank, is destined for installations, where a second back up heat source is present. A back up heat source, can be an oil or gas boiler, a heating element, or even a biomass boiler.
Even with no sun, through our solution, you can enjoy a hot water bath.
Every storage tank, is vertical, with a PVC outer cover.
In case of outer space installation, it can be equipped with steel cover.
Sigma Energy, posses the technical know-how, in order to engineer, and supply forced circulation systems, for domestic, commercial or industrial use.
